Question 1: Why is the output voltage lower than the nominal voltage
Answer 1: This may be due to excessive load or insufficient power supply
Question 2: Why is there no negative voltage output or the output is too low?
Answer 2: Negative voltage cannot be used alone. When using negative voltage, the same load must be applied to the positive voltage terminal.
